A composer’s demo can win the room. It can also become the most fragile asset in the production if everyone starts treating it like cleared campaign music.
The issue is not just legal. It is practical. Can the agency keep the demo under the director’s cut? Can it go into consumer testing? Can the brand present it to retail partners? Can it run online if the composer only sent it for a pitch?
The safe answer is simple: not until the usage has been checked and agreed. A demo is not automatically a licensed track. It may include an original composition, third party sounds, guide vocals, sample material, temporary programming, session players, or a creative direction that was never intended to leave the edit suite.
For producers, the right question is not “do we like it?” The right question is “what exactly are we allowed to do with it?”
A demo is not a broadcast license
In advertising, the word demo covers many things. It can mean an original cue written for a competitive pitch. It can mean a sketch to prove tempo and tone. It can also mean a very rough file built from commercial sound libraries, virtual instruments and temporary ideas that were never meant to survive into final delivery.
That distinction matters.
A track sent for creative review does not automatically include permission for TV, cinema, social paid, online video, retail, out of home, events, trailers or case studies. In France, the copyright code requires transferred rights to be specified and the field of exploitation to be delimited by scope, purpose, place and duration. In the UK and US, the rules are framed differently, but official guidance still points back to the same operational truth: ownership and usage depend on the creation context and the written agreement.
The production mistake is assuming that because the composer made the file for the job, the brand can use it for the campaign.
The five checks before approval
Before keeping a demo, ask five questions.
First, who made it? Was it written by one composer, or did a producer, co-writer, arranger, vocalist, musician or sound designer contribute? If there are multiple contributors, their roles and rights need to be clear before usage expands.
Second, what comes from third parties? Sample packs, loops, vocal fragments, presets and licensed sound libraries have different rules. Many are safe inside a finished composition. Some are not safe if exposed, resold, used as a sonic logo or relied on as the main hook.
Third, is it technically fit for delivery? A demo may feel perfect against picture but fail in final mix. It may not have stems, alt endings, no-vocal versions, broadcast headroom, social cutdowns or enough space for dialogue and sound design.
Fourth, did the composer agree to campaign use? A pitch fee is not the same as a usage fee. A speculative demo may be made for listening, comparing and selecting, not for public release.
Fifth, does the budget match the ambition? If the brand wants exclusivity, multi-territory usage, long term media and versioning, the music deal needs to reflect that.

Concrete example: the test track becomes the campaign
Imagine a beauty film cut to a bespoke demo. The music is restrained: prepared piano, granular electronics, a processed female breath and a small orchestral lift in the final ten seconds. The board loves it. The brand decides to run the film as paid social across six markets.
That is the moment to pause.
Was the breath recorded by the composer, a session vocalist, or pulled from a library? Was the performer released for advertising? Are the electronic textures safe for a multi-market campaign? Does the brand need the master only, or rights in the composition as well? Can the cue be cut into 6, 10, 15 and 30 second versions without new composition? Who will deliver stems and mix alternates?
The correct production move is to convert the demo into a formal music commission. Define media, territory, term, exclusivity, master ownership or license, publishing position where relevant, performer releases, deliverables and fee. Only then should the track move from “we like it” to “we can air it.”
This is close to the temp music problem. A temporary track helps decision making, but that does not make it usable. We cover that risk in our article on <a href="https://sultasto.agency/blog/en/temp-music-commercial-rights-2026-10-23">temporary music in advertising</a>.
License, buyout or rebuild?
There are three sensible routes.
The first is licensing the demo as it stands. This can work for a short campaign with limited media if the rights chain is clean and the mix is deliverable. It is usually the fastest option, but only when the demo was built from safe material.
The second is a broader buyout or assignment. Brands sometimes want this when the music has become strategically important, when it might develop into a sonic identity, or when competitor conflict matters. But the scope must be precise. Buying the master is not always the same as controlling the composition, publishing, neighbouring rights or future adaptations.
The third is a controlled rebuild. Keep the musical idea, but produce it properly: clean session, cleared players, approved samples, usable stems, final mix, cutdowns and written rights. This is often the best option when the demo contains too many temporary elements.
The right choice depends on actual use. A three month UK web film is not the same as a global platform with social, retail, event screens and brand toolkits.

The serious objection: this can slow the job down
The objection is fair. Advertising schedules are compressed. Nobody wants a promising music route to stall because a demo needs paperwork.
The answer is not to over-lawyer every sketch. The answer is to separate uses.
For internal review, a short pitch agreement may be enough if it says the track is confidential, non-broadcast and not reusable without permission. For external testing, the permission should be more explicit because the track has left the project team. For public release, there must be a proper license or transfer.
This staged approach protects momentum. It avoids negotiating a worldwide buyout before the brand has chosen a route. It also avoids discovering at final mix that the preferred cue cannot be used.
The production decision
If the demo is only a guide, treat it as a guide and commission a clean final track. If it has become irreplaceable, treat it as campaign music immediately.
Ask for a rights memo before final creative approval: contributors, third party elements, performers, collecting societies, requested usage, term, territory, media, exclusivity, deliverables and fee. It does not need to be long. It needs to be unambiguous.
At Sul Tasto, this work protects both the film and the music. A demo can be a strong creative instinct. To become an advertising asset, it has to become a properly produced and properly licensed piece of music. If everyone wants to keep the temporary cue, make the call before final mix, not after.
